First time here ever at in and out and the experience was great! We were informed that we can get these “dine in” trays for us to eat in the car and I thought that was very neat! The staffs were wonderful and very friendly and the food was 10/10. I got the “protein style” cheese burger, which was cheese burger wrapped with deliciously crisp and fresh lettuce.

There’s something about In-N-Out Burger that continues to captivate me. Every time I go, it’s not just a meal, it’s an experience that never disappoints. The burger itself is a masterpiece – every bite is a blend of flavors that somehow manages to excite my taste buds every single time.

This place rocks! Everything was wonderful! MY FAVORITE PART IS THEY GIVE YOU A NICE BREAK IN PRICE IF YOU DON’T WANT BUN OR VEGIES! I ORDER THE FLYING DUTCHMAN, (meat & cheese only). You even get more of a price break on meat only. We like to stop in for a light lunch while out shopping. It would be nice if more places catered ti the carnivore way of eating.

Fun isn’t great, I just don’t like the meat and I wasn’t raised on this style so it holds nothing for me. Service is generally with a smile, so they do a good job there, but the atmosphere reminds me of Taco Bell circa 1985. Not a bad place, but I’m not a cheerleader for them either. Meets the need for low price food when I’m hungry

Great location. Fast, friendly customer service. Super hot, fresh food. I ordered the #1 (double-double; fries; drink). It came out to about $12. Great price for a delicious meal.

I like the concept, the place was packed and slow. The food was decent I expected fresh burgers but I think it was a processed patty. The shake was great. The presentation was really nice. I think I just need to try them again, I was not impressed this time. But my boys loved it so maybe because my order was delayed I didn’t fully enjoy it.

This was my first time going to an In-N-Out. the staff were friendly and you could tell it was high quality just by taking a look at the kitchen. In my opinion though the taste is just about like any other fast food place. It’s still worth trying at least once.

Fast service, friendly workers, the food quality was fantastic, a lot of food for the money we spent. I had a root-beer float it had a little more root-beer in it than I like but it was still pretty good. I highly recommend eating here.

In my opinion, this place didn’t leave a lasting impression. The menu is quite limited, offering only a few options, and the food itself is rather ordinary. One can find a similar burger at Dairy Queen or Sonic with a wider variety of choices. It would be nice if they included alternatives like onion rings or tater tots, as not everyone enjoys French fries. On a positive note, the milkshake was enjoyable, although it essentially consists of ice cream and milk. If you prefer simplicity, this place may suit your taste, but don’t anticipate a lower cost despite its straightforward offerings.
